@18: Not sure where you read that. If you look at pictures from the Royal Variety Performance, there are people with bare arms and deep cleavage - and Catherine has bare arms in these pics.
I think Catherine looks gorgeous. The Reiss website crashed with everyone trying to buy that dress.
Mrs. Obama - I think she looks like she's wearing drapes from a cheap chinoiserie shop. It's too evening for a daytime event, and it does nothing for her figure. This one is a no from me.

Does anybody know where Kate´s dress comes from? It looks great, a bit like Roland Mouret or even Victoria Beckham. I agree with those who says that Michelle Obama needs to tone it down. She set out to be such a stylish First Lady but most of the time, she looks like she tries too hard with too many colours and too much volume. Her outfit here makes her fit right into the British royal family, and that´s not good...

Kate looks like she's born for this stuff. The President and the First Lady are ole pros at this stuff now. I do agree a less puffy dress would have worked better on the First Lady. Prince William looks happy.
